381 1@0 Specification of Letters Patent. Pgatgntgfl Ju e 14 1921 Application filed October 15, 1920. Serial No. 417,185.

T 0 aZZ whom it may concern W Be it known that I, MANFRED ii0LMES Aannzosn, a citizen of the United States;

residing at Springfield, in the county 0 certain new .and useful Improvements i lVheels, of which the following is a spec fication, reference being had therein to th accompanying drawing.

My invention relates. to'wh'eels for ve-i hicles and in partlcular to wheels for auto-g mobile equipment.

The object of my invention is to providef a resilient structure which shall have the necessary rigidity at the points of strain but shall eliminate the necessity for a pne matic tire.

ber between the hub and rim, a resilient rim and in the place of the ordinary spaces between the spokes to Provide comparatively rigid braces.

leferring to the drawings:

Figure 1 is a side elevation of my wheel.

Fig. 2, is a transverse section on the line 22 of Fig. 1.

Referring to the drawings, numeral 1 represents a disk-like body composed preferably of flexible and resilient material such as rubber or its equivalent, the same having a central opening 2 and being provided on each side of said opening with hub plates 3 having each an opening 4 corresponding with the central aperture 2, the purpose of the openings being to permit of the introduction of a bushing and axle not shown. The hub-plates 8 are composed of metal and secured to the body 1 by means of bolts 5 which extend through the plates on the opposite sides, and are fastened by nuts 6. The plates 3 as shown, are preferably of a configuration resembling a five-pointed star, having equidistantly spaced radial strengthening fingers or spoke-like members 5.

Equidistantly spaced between the starlike fingers 5 the body 1 is provided with a series of apertures 9 which are largely covered by supporting and cooperating reinforcing plates 10 having arms 11 somewhat similar in shape to the arms of a Maltese cross, the outer ends of each of which arms however, being so rounded that It is particularly useful on!v trucks and upon lighter vehicles.

It is my object to, generally, reverse the: ordinary practice of having rigid hub, spokes and rim by providing a resilient disk mema line joining the arms would form ap- Extending through proximately a circle. each arm is a bolt 12 passing through the body 1 and united to a similar supporting Clark and State of Ohlo, have lIIVBIItBCl )late on the other side thereof by means of t nut 13. These plates like'the ones formng the hub support are of metal though 1 preferably of a somewhat thinner or lighter tructure than the hub plates. ,Theouter peripheral edge of the body 1 s surrounded by a solid tire 14 closely fitted thereon and firmly held in position by metallic tire holding plates 15 of a general rlangular shape, bolted to the body 1 by means of bolts 16 passing through the structure and firmly held to like plates'16 on he opposite side. I

It will be observed that besides the hub plates 3, bolted on each side of the body, he other plates mentioned when combined with said hub plates fairly well cover the sides of body, to which they are yieldingly but securely attached by means of the bolts. This gives rigidity to the structure as a whole and yet at the same time the flexibility and resiliency in the body absorbs such shocks as may be received by the wheel in translt.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. An automobile cushion wheel comprising a disk of resilient material, an aperture through the center thereof, a hub plate on each side with an aperture, corresponding to the aperture in the disk, other apertures in the disk located equidistantly between the hub plates and the periphery of the disk, cooperating reinforcing plates positioned over said last mentioned apertures and a tread portion fastened to the disk by tire clamping plates.

2. An automobile cushion wheel comprising a disk of resilient material, an aperture through the center thereof, a hub plate on' each side with an aperture corresponding to the aperture in the disk and having radial ture through the center thereof, a hub plate on each side provided with equldistantly spaced fingers and an aperture corresponding to the aperture in the disk, other aper tures in the disk located equidistantly between said fingers of the hub plates, Cooper ating reinforcing plates fastened over said last mentioned apertures and a tread por tion fastened to the disk by tire clamping plates. i

a. In an automobile cushion wheel corn-. prising a disk of resilient rnateriahan aperture'through the center thereof, a hub plate on each side with an aperture corresponding to the aperture in the disk and having radial strengthening fingers, other apertures equidistantly located between the radial strengthening fingers of the hub plates and the periphery of the disk, cooperating reinforcing plates fastened over said last mentioned apertures and a tread portion fastened to the disk by tire clamping members.

5. In an automobile cushion wheel comprising a disk of resilient material, an aperture through the center thereof, a hub plate en each side with an aperture corresponding to the aperturegin the disk, other apertures'in the disk located equidistantly between the hub plates and the periphery of the disk, cooperating reinforcing plates whose shape is substantially that of a Maltese cross positioned over said last mentioned apertures and a tread fastened to the disk by triangular tire clamping plates.

In testimony whereof, I affix my signature.

MANFRED H. AMBROSE.
